Its been no secret that Manchester United have struggled in the central-midfield area in recent years.
Michael Carrick's form has kept things ticking over in the middle of the park, and Paul Scholes' return from retirement certainly helped.
However, with Scholes now retired for good, and Carrick at 32-years of age, David Moyes must sure up his midfield.
Recent reports have suggested that United will make a fresh bid for Everton star Marouane Fellaini, as-well as targeting Real Madrid ace Luka Modric.
And, if these deals can be pulled off, the midfield duo could be the men to bring Champions League success back to Old Trafford.
Fellaini would certainly offer the Red Devils something different - he can act as a box-to-box midfielder, can play off the striker and can sit in-front of the defence.
And, if there's a manager who knows when to play him and how to use him, it's David Moyes.
Additionally, the Belgian international would give United extra strength in the air, both in attack and in defence.
Last season, when United were knocked out against Real Madrid, the Belgian could have excelled against the La Liga outfit.
He could have used his power and presence to put the Red Devils into the quarter-finals.
Of course, on that occasion, Nani's sending off changed the game, but had the Belgian been there to protect the defence, perhaps United would have not lost their advantage so easily.
And, the man that scored that vital goal at Old Trafford, (no, not Ronaldo) Luka Modric could then be the missing link in the jigsaw at United.
The Croatian star was full of class in the Premier League as he played for Tottenham and, at Manchester United, he could light up the European stage.
With Carrick, Modric and Fellaini being rotated in central-midfield and the quality going forward of Robin van Persie, Wayne Rooney and Shinji Kagawa, then United would certainly be set-up for a European challenge.
David Moyes may have little Champions League experience, but if Fellaini and Modric can be added to his side, then United can be kings of Europe again.
